- The carbon cycle is the process in which carbon travels from the atmosphere into organisms and the Earth and then back into the atmosphere. Plants take carbon dioxide from the air and use it to make food.Animals then eat the food and carbon is stored in their bodies or released as CO2 through respiration.arbon is also found abundantly in our atmosphere in the form of carbon dioxide, or CO2. Additionally, carbon is also trapped within the Earth in the form of fossil fuels. The carbon cycle is essentially nature's way of reusing carbon atoms in different ways and in varying places.

carbon cycle The continuous process by which carbon is exchanged between organisms and the environment. Carbon dioxide is absorbed from the atmosphere by plants and algae and converted to carbohydrates by photosynthesis. Carbon is then passed into the food chain and returned to the atmosphere by the respiration and decay of animals, plants, and other organisms.

What is The Carbon Cycle? Carbon Moves between Sources and Sinks. One important aspect of the carbon cycle is the speed with which carbon moves from a carbon source to a carbon sink and then back again. Some living things grow and decompose more quickly than others.

Calvin cycle The Calvin cycle is the principal mechanism that leads to the conversion of carbon dioxide into sugars by plants, algae, photosynthetic bacteria, and certain other bacteria that use chemicals as an energy source instead of light.

The Biological Carbon Cycle Mouseover the pictures and arrows to learn more In the geological carbon cycle, carbon moves between rocks and minerals, seawater, and the atmosphere. Carbon dioxide in the atmosphere reacts with some minerals to form the mineral calcium carbonate (limestone). Cars that pollute the environment less than standard gasoline-powered cars.

The Carbon Cycle and Long-Term Carbon Storage The Carbon Cycle. Perhaps the most studied biogeochemical cycle is the carbon cycle, which, as you may have guessed, describes the pathways that carbon takes through living organisms and the environment. The carbon cycle is very different from either the nitrogen or phosphorus cycle. One reason is that the primary source of usable carbon for plants is carbon dioxide in the atmosphere, not the soil, which is where the main sources of phosphorus and nitrogen are for terrestrial plants. Because carbon dioxide is a gas that can move freely through the air and water, the carbon cycle is truly global.

- The carbon cycle is the circulation of carbon atoms between the ocean, land, and atmosphere by physical, chemical, and biological processes. Living organisms are of great importance in the carbon cycle, because life on planet Earth is comprised of carbon compounds such as proteins, carbohydrates, and lipids.

- It takes many forms and moves through the environment via the carbon cycle. The carbon cycle is the circulation and transformation of carbon back and forth between living things and the environment. Carbon is an element, something that cannot be broken down into a simpler substance.

Carbon dioxide Carbon fixation is a biochemical process by which atmospheric carbon dioxide is incorporated by plants, algae and (cyanobacteria) into energy-rich organic molecules such as glucose, thus creating their own food by photosynthesis.arbon dioxide exists in the Earth's atmosphere as a trace gas at a concentration of about 0.04 percent (400 ppm) by volume.

The Carbon Cycle Steps The Carbon Cycle Step 2. Carbon dioxide is absorbed by producers (life forms that make their own food e.g. plants) to make carbohydrates in photosynthesis. These producers then put off oxygen.

Carbon cycle The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.arbon also exists in various forms in the atmosphere. Carbon dioxide (CO 2) is partly responsible for the greenhouse effect and is the most important human-contributed greenhouse gas. In the past two centuries, human activities have seriously altered the global carbon cycle, most significantly in the atmosphere.

Ecology/Biogeochemical cycles Carbon is exported from a cycle in the form of CO 2 via respiration of all living organisms. The most important biogeochemical cycles are the carbon cycle, nitrogen cycle, oxygen cycle, phosphorus cycle, and the water cycle. The biogeochemical cycles always have a state of equilibrium. The state of equilibrium occurs when there is a balance in the cycling of the elements between compartments.

Carbon Cycle The carbon cycle is one of several key biogeochemical cycles linking the biosphere, atmosphere, geosphere, and hydrosphere. It is no longer in a state of equilibrium as a result of burning fossil fuels and converting forested land into low-carbon alternatives.

Revision:Gcse biology - diffusion Diffusion in plants. Diffusion – The passive movement of particles from an area of high concentration to an area of low concentration For photosynthesis to occur carbon dioxide must diffuse into the leaf (via the stomata) to the cells (especially the palisade cells).

What is The Carbon Cycle? Carbon is present throughout the natural environment in a fixed amount. It takes many forms and moves through the environment via the carbon cycle. The carbon cycle is the circulation and transformation of carbon back and forth between living things and the environment. Carbon is an element, something that cannot be broken down into a simpler substance. Other examples of elements are oxygen, nitrogen, calcium, iron, and hydrogen.

What is the Carbon Cycle? What is the science behind it? The Slow Carbon Cycle 'Through a series of chemical reactions and tectonic activity, carbon takes between 100-200 million years to move between rocks, soil, ocean, and atmosphere in the slow carbon cycle. On average, 1013 to 1014 grams (10–100 million metric tons) of carbon move through the slow carbon cycle every year. In comparison, human emissions of carbon to the atmosphere are on the order of 1015 grams, whereas the fast carbon cycle moves 1016 to 1017 grams of carbon per year....'.

CONTENTS The process of absorbing carbon dioxide and releasing oxygen is called gas exchange (or gaseous exchange).   Molecules of carbon dioxide enter the plant, and molecules of oxygen leave the plant, by a process called diffusion.

- Interactive: Carbon cycle. Carbon dioxide is one of the most important gases that dissolve in the ocean. Some of it stays as dissolved gas, but most reacts with the water to form carbonic acid or reacts with carbonates already in the water to form bicarbonates. This removes dissolved carbon dioxide from the water.nteractive: Carbon cycle. Carbon dioxide is one of the most important gases that dissolve in the ocean.

What is the Carbon Cycle? What is the science behind it? (Illustration adapted from P.J. Sellers et al., 1992.). Plants and phytoplankton are the main components of the fast carbon cycle. Phytoplankton (microscopic organisms in the ocean) and plants take carbon dioxide from the atmosphere by absorbing it into their cells. Using energy from the Sun, both plants and plankton combine carbon dioxide (CO 2) and water to form sugar (CH 2 O) and oxygen.
